A researcher has a very small sample of DNA and needs to make millions of copies in order to study a specific gene. Because the original amount of DNA is insufficient for experiments like sequencing or cloning, the researcher decides to use a laboratory technique that can rapidly amplify the DNA. Question:Which technique should the researcher use to amplify the DNA, and what is the basic principle behind it?

A microbiology researcher is studying Serratia marcescens, a bacterium known for producing a red pigment called prodigiosin. The researcher notices that when the bacteria are grown at 25°C, colonies develop a deep red color, but when grown at 37°C, the pigment production is greatly reduced, and colonies appear pale or colorless. The researcher hypothesizes that temperature affects the expression of genes involved in prodigiosin synthesis. Which explanation best accounts for the difference in pigment production at 25°C versus 37°C? [color1] If a mutation occurred in the regulatory region controlling prodigiosin genes, what would be the expected result at 25°C? [color2] Which experiment would best test whether temperature affects transcription or enzyme activity in prodigiosin synthesis? [color3] Why might S. marcescens benefit from producing pigment at lower temperatures but not at human body temperature (37°C)? [color4] If you wanted to engineer a strain of S. marcescens to produce pigment at 37°C, which approach would be most effective? [color5]
